It’s really simple. So simple that I felt like an idiot when I did not get it to work right away. If you have a motherboard from Intel’s Extreme or Media series, you probably have CIR headers (some other manufactures have them as well, but it’s rather hit or miss). CIR is an acronym for Consumer InfraRed, is a standard of sorts that allows us to do fun things like turn on our HTPC with a standard IR remote. Best of all (sort of), it doesn’t require a USB adapter.
